The left with say it's trumps fault, the right will say it's the globalists, the centrists will probably say something like it's just normal US policy. Even if Syria doesn't become a flash point, there is still the nuclear issue with North Korea and the South China Sea as flash points.
You in fact have already stated the left's opinion "if trump gets us into ww3" so, no, there won't be any unity, civil war or marshal law are far more likely.
